For me DC is peak because it's the best addition to the game compared to what came before it. WA was pretty cool although the faction pairings were kind of funny. Meanwhile DC adds two good factions, introduces a new campaign mode and still manages to throw out some new units and skirmish maps. Plus if you were a poorfag you only needed it to play online (I forget if single player modes had the same restrictions to faction selection)
Meanwhile SS has essentially the same campaign but with less SOVL, two factions that are a bit weak and a new type of unit that no one likes. It's got the most content and fixed some bugs and balancing fuckery so it is still the best but DC definitely added more.
I do still wish Iron Lore got the chance to do more, as a little bit of campaign polish and improvements to the souls/faith system would have gone a long way. They also wanted to add different units IIRC, but were forced to abandon them due to time constraints after Relic insisted on flying units.
